An apparatus and method for removing a jammer signal in a wireless
communication receiver, in which a frequency converter down-converts a
radio frequency (RF) signal including a desired and a jammer signal into
a baseband signal. A first filter removes the desired signal from an
output signal of the frequency converter and outputs a jammer signal as
an output signal. The frequency converter up-converts the jammers signal
output from the first filter. The second filter outputs the up-converted
jammer signal as an output signal. The first adder receives the RF signal
and the output signal of the second filter and removes the jammer signal
from the RF signal using the RF signal and the output signal of the
second filter. Accordingly, the frequency converter down-converts the RF
signal including the attended jammer signal.
